Features

Zenith simplifies your interactions with your Zebra full node, providing an interface that allows you to:

Zenith GUI

Create and manage multiple wallets.
Create and manage multiple accounts and addresses per wallet.
View your Zcash balance and see your transactions and shielded memos.
Send Zcash transactions to Unified Addresses, Sapling addresses, transparent addresses and TEX addresses.
View the value of your ZEC balance in the currency of your choice.
Generate and accept Payment URIs.
Generate and import Unified Viewing Keys.
Importing existing wallets from a seed phrase.

Zenith also has a Text User Interface (TUI) for users that may not have access to a graphical desktop environment.

For more advanced use cases, Zenith includes a RPC server that allows programmatic access to the wallet and the Zcash blockchain.

Zenith is an open source application written in Haskell, generously supported by Zcash Community Grants and is available in our code repository.

Zenith Privacy Levels

Starting on version 0.7.0.0-beta, Zenith offers their users a set of policies to manage the information they want to disclose in their transactions in a simple way.

We have four levels, Full, Medium, Low and None.

Full

This policy only allows sending funds within a shielded pool. It does not allow for transfer across shielded pools.

Element	Is Private?
Sender
Receiver
Amount

Medium

This policy allows funds to cross shielded pools, which does reveal the amount transferred.

Element	Is Private?
Sender
Receiver
Amount

Low

This policy allows funds to be transferred outside of the shielded pools into the transparent pool. This reveals the amounts as well as the receiver of the funds.

Per ZIP-320, this policy will not allow sending of funds to a TEX address to avoid loss of funds.

Element	Is Private?
Sender
Receiver
Amount

None

This is the only policy that allows the spending of transparent notes in the wallet. This policy only allows transparent receivers, including TEX addresses per ZIP-320.

Docker Image

Requirements

Installation

Validate the Zenith package signature using minisign:

minisign -Vm zenith-docker_0.9.1.0.7z -P RWSEl9L5g2laFaUwUmdXtqgFJGeKenajJ0Im7lMNe877VKSBGSpTeFEh

Unpack the Zenith package:
```
7z x zenith-docker_0.9.1.0.7z
```
A new folder named zenith-docker_0.9.1.0 will be created. This folder contains the installation package.
Setup the Zenith Docker image using the provided script:
```
cd zenith-docker_0.9.1.0
./setup_docker
```
This command will install or update Zenith on your computer.

If you have an existing installation of Zenith, you will need to backup your zenith.db file and restore it into the ~/Zenith directory if you want to continue to use those spending keys. Otherwise, Zenith will create a brand new wallet on start-up.

This release includes changes to the internal database schema that require a full re-scan of your wallet. This may take some time but it is only required during the schema migration.

Adjust the provided configuration file on ~/Zenith/zenith.cfg with your Zebra node's host and port and the credentials for the RPC server.
Open a console window, run the Zenith container with the provided runzenith script, starting the Zenith GUI.

If you are installing on a computer without a graphical desktop environment (like a VPS), use runzenith --expert to start the Docker console where Zenith’s commands can be issued:

$ runzenith --expert

=============================================
Welcome to Zenith Full Node Wallet enviroment
v0.9.1.0

zenusr@hwsrv-1214154:~$ zenith tui

To display all available options you can use -h switch.

$ runzenith -h

       -r | --rpc    -> starts zenith\'s rpc server
       -h | --help   -> displays this screen

Installation from Source

Install dependencies:
- Cabal
- Zebra
- Cargo
- Install cargo-c:
```
     cargo install cargo-c
```
- xclip
- libsecp256k1-dev
- libxss-dev
- libxrandr-dev
Clone the repository.

git clone https://git.vergara.tech/Vergara_Tech/zenith.git
cd zenith
git submodule init
git submodule update --remote

Run the configure script:

$ ./configure

Build using cabal:

$ cabal build

Install the executable:

$ ./install

Run Zenith:

$ zenith gui

Configuration

You need a zenith.cfg file present in the ~/Zenith folder with the following fields:

nodeUser: The user that the RPC server will use for authentication.
nodePwd: The password the RPC server will use for authentication.
nodePort: The port the RPC server will use. Default is 8234.
dbFileName: The name of the wallet’s database. Default is zenith.db.
zebraHost: The host where Zebra is running. Zebra must be configured to not use cookie authentication.
zebraPort: The port where Zebra’s RPC server is available.
currencyCode: The currency code for ZEC exchange rate (usd, eur, gbp, etc).

Usage

Note: This is beta software under active development. We recommend to use it on testnet. Zenith runs on the network Zebra is running, to use the testnet you need to configure your Zebra node to run on testnet.

Graphical User Interface

To start in graphic mode, use zenith gui

Zenith will attempt to connect to the node and start up, the app will guide you through the creation of the first wallet.

We recommend you back up your wallet seed by clicking the menu and the Backup Wallet button.

Demo

Text User Interface

To start in text mode, use zenith tui.

Zenith will attempt to connect to the node and start up, the app will guide you through the creation of the first wallet.

We recommend you back up your wallet seed by pressing the W key to display the Wallet menu, and then the S key to display your seed.

Zenith displays the different actions and their hotkeys highlighted in green:

RPC Server

The Zenith RPC server is distributed as a separate binary, zenithserver:

$ zenithserver
Zenith RPC Server 0.9.1.0-beta
------------------------------
Connected to TestNet Zebra v2.2.0 on port 18232

The available RPC methods are described in detail in the Zenith OpenRPC spec.

For a demo of interacting with the RPC server, see the screencast below:
